Vodacom poor service.

Vodacom informed me a more than a month ago that when they sold my home internet to me they never check if I had signal, and that's why I had poor reception. They they informed me that they would be canceling the contract at their cost, because they confirmed that there was not reception in our area. After many phone calls up to today they keep saying its a back office process, and that cancelations can not assist. I am still paying for something I do not get, and Vodacom call center is just such a terrible place to call. You hold on for up to 30 minutes just to be told they can not assist.
